Improvement of Recommendations for Potash Fertilizer Use and Adjustment of Currently Used Soil Potassium Test Interpretation Classes in Intensive Cropping Systems

The project has the following goals: a) determine optimal potash fertilizer rates for major crops in crop rotation that have a high demand for potassium, b) evaluate the validity of currently used soil test potassium interpretation classes for proper assessment of plant potassium requirements, c) develop proposals to the Ministry of Agriculture on possible fine-tuning of current practice to develop K fertilizers recommendations and adjustment of currently used soil test potassium interpretation classes. Locations of field experiments - Lipetsk, Voronezh, Belgorod, and Rostov Oblasts (Russia). Soil types - Chernozem soils with medium and “increased” (higher than medium) content of routinely extracted potassium. Crops - sugar beet, grain maize, rapeseed, soybean.

IPNI-2012-RUS-1

During the last 15 years in Russia, both nutrient rates and ratios were changed with a decline in the relative share of phosphate and potash fertilizers relative to N fertilizer. The adjustment of nutrient rates considering soil type, fertility status, and crop management factors has, thereby, high priority for research experiments in current cropping systems. With long-term removal of K exceeding K inputs negative K budgets are being observed in various agricultural zones of the country. Read more

Interpretive Summary

This five year project located in Lipetsk, Voronezh, Belgorod, and Rostov oblasts has a special focus on the efficiency of the direct and residual effects of potassium chloride (KCl) for three subsequent crops in rotation. The single application of KCl was only applied to the first crop in rotation (sugar beet, grain maize, rapeseed, or soybean). For the next two crops in rotation the residual effect of KCl was studied.

This three-year project has a special focus on optimization of K fertilizer application rates for crops with high response to K, such as sugar beet, maize, rapeseed, and soybean.

This 3-year project has a special focus on optimization of fertilizer K rates for crops with high response to K, such as sugar beet, grain maize, rape, and soybean.

During the last 15 years in Russia, both nutrient use (rates) and ratios have changed with a larger decline in the share of P and K fertilizers relative to N fertilizer. The adjustment of nutrient rates considering soil type, fertility status and crop management factors has, therefore, gained high priority for research experiments in current cropping systems. With long-term removal of K exceeding K inputs, negative K budgets are being observed in various agricultural zones of the country.
